GO enrichment analysis

Gene Ontology (GO) term enrichment is a technique for interpreting sets of genes making use of the Gene Ontology system of classification, in which genes are assigned to a set of predefined bins depending on their functional characteristics.

In an enrichment analysis, we take a set of differentially expressed (DE) genes and check to see if any of the gene sets (here from the GO sets) are found in our set of DE genes than you would expect at random. *If you want to get into the math, the main statistic used for these types of analyses is a hypergeometic test

There are 3 different domains in the GO tree: Biological processes (often the most relevant), cellular component (i.e. where the genes’ proteins are located) and molecular function (i.e. enzymatic function). We look at them separately here using only the genes with an adjusted pvalue of less than 0.05 and at least an absolute log2FC of 0.5849625 as our set of differentially expressed genes (these cutoffs are fairly abritrary, but were chosen to give us a set of genes taht were significant and had at least some change in expression). A GO category is considered enriched if the statistical test returns an adjusted pvalue (for multiple testing) of less than 0.05.

KEGG analysis

Here we do the same type of enrichment analysis, but using the genes in KEGG defined pathways as gene sets instead. We use the same definition of DE genes.

> kegg <- enrichKEGG(gene = sigEntrez, universe = allEntrez, organism = params$species, 
+     pvalueCutoff = alpha)
> saveData(kegg_lungnotumor_tumor, dir = dataDir)

GO GSEA analysis

A common approach in analyzing gene expression profiles was identifying differential expressed genes that are deemed interesting. The enrichment analysis we demonstrated previously were based on these differentially expressed genes. This approach will find genes where the difference is large, but it will not detect a situation where the difference is small, but evidenced in coordinated way in a set of related genes. Gene Set Enrichment Analysis (GSEA) directly addresses this limitation. All genes can be used in GSEA; GSEA aggregates the per gene statistics across genes within a gene set, therefore making it possible to detect situations where all genes in a predefined set change in a small but coordinated way.

GSEA relies on ranking genes. Choosing a metric to rank by is an important decision which affects the interpretation of the results. Here we rank them by a metric based on their -log(pvalues), but modified by the sign of the log2FC (i.e. upregulated and downregulated genes will be put at opposite ends of the ranking). This will result in a gene ranking where the significance of the gene expression change determines ranking and negatively and postively regulated genes are treated as being different.

## Error in is.data.frame(x): object 'gsesignedpvalueSummary' not found

> gsesignedpvalueSummary %>% datatable()

## Error in eval(lhs, parent, parent): object 'gsesignedpvalueSummary' not found

There is nothing enriched when we treat the direction of expression important. This may be because GO categories are not necessarily sets of coregulated genes, and the method we used will find sets of genes that are upregulated together OR downregulated together, rather than both.

KEGG GSEA analysis

We can also perform GSEA analysis with clusterProfiler using KEGG gene sets and using the log2 fold changes as input. By using the log2 fold changes as the input, we are identifying pathways with genes that exhibit coordinated fold changes that are larger than might be expected by chance. The significant pathways can be visualized using the log2 fold changes with the Pathview tool.

Methods

RNA-seq counts were generated by bcbio and bcbioRNASeq using salmon (Patro et al. 2017). Counts were imported into R using tximport (Soneson, Love, and Robinson 2016) and DESeq2 (Love, Huber, and Anders 2014). Gene annotations were obtained from Ensembl. Plots were generated by ggplot2 (Wickham 2009). Heatmaps were generated by pheatmap (Kolde 2015).
